HVAC SYSTEM RE-QUALIFICATION PROTOCOL

Hold the anemometer-fan about mm from filter face for measuring the filter face velocity and for checking the uniformity of velocity.

System composed of filter and grid support system or other housing mounted in the ceiling wall, apparatus or duct. In case it is found to exceed the upper limit, a gas cut silicon is used to decrease the leakage. The sterile area is validated through following tests. Scanning shall be done at the rate of maximum 2 feet per minute. Notify me of new posts by email.

The particles should be count when more than one hour work has been progressed in the area.

HOW TO VALIDATE AHU IN INDUSTRY(AIR HANDLING UNIT)

Turn on the AHU and record the particle count for a 6 second period each minute, until the cleanliness level at the outlet is restored to the original condition. Observed and calculate the total air change in the room. Hold the fan of the anemometer till the anemometer reading is stabilized for at least 10 seconds duration and values should be recorded.

The damper can be adjusted depend upon the design requirement. What is Calcium Carbonate? Particle count is taken before the operation as well as during the working condition. Photometer detects the leak of every 2 seconds.

The different media plates are exposed in every manufacturing section including the reverse air duct of the HEPA filter at the phqrma of the cubicle. This should not take more than 15 min. To determine the air borne microbial contamination level in air for the Sterile Corridor. First look at Air Handling Unit Definition.

The total air change is calculated. Room in which the concentration of airborne particles is controlled and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the room and which other relevant parameter.

Plate shall be exposed for 4 hours.
